Beit known that L @immun ESWICK, a citizen ofthe Tihnted States, residing at' Weston, 4in the county of Lewis and State of Test Virginia, have invented a new and useful E; on Skid Automobile l Chain, of 1which the Jfollowing is a specification.

The device forming the subject matter of this application lis a protector or guard adapted to be applied to a pneumatic ltire for Y the double purpose of preventing* wear on the tire and ireventing shielding;

l`he 'invention aims, primarily, toprovide novel means for operatively assemblingthe constituent sections oiithe 'protector .or guard.

lt within the scopeoi the invention to improve thegcneralconstruction of the 4sections which malte up the guard.

'lilith the above and other objects in view which ivillappear as the description pro (feeds, the invention resides in the combinationI and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made Within the'scope ot' what is claimed. Without' departing troni the spirit or the invention.

ln the accompanying drawing-Figure lfshoivs in side elevation. a wheel the tire of which is equipped. with the 4protector or 'guard formingr the subject matter of this applicationshin. 2 a cross section: Fig. 3 shows the VWheel ot' Fig. 1 viewed edgewise and in elevation; Fig. is a section on the lined-L of Fig. 1; Fig. 5 is a section on the line 5 5 of Fig. il; Fig. 6 is a perspective of one of the links; Fig. 7 is a perspective showing the connecting' levers and the link which is assemble-d therewith.

- The tire protector constituting the subject matter of this application comprises any desired number oi troughshaped sections which preferably are fashioned troin'steel and i'rf desired from resilientsteel. in the present instance the protector is shown as comprising tour sections Vnurnbered respectively i, 2, 3 and i on the drawings,

rihe sections 1' and-2 are alike, each of the sections l and 2'being provided at one end with relatively small Wings 5, and `being` provided at its other end with larger wings ti, The Wings and 6 ot' the vrespective sections are disposed adjacenteacb other. Une end ot the section. 3 is provided with small Specification oi Letters Patent.

posed adjacent wings 8 on the section t, the

section 4 having .wings 9 ,which are spaced from' the wings 8'. F rom the Wings 9, outstanding, hook-shaped lips or lever stops l0 are struck. A

65 'Each of the Wings o 1s provided-Wdh an opening 11 and in the adjacent end of the Wing (l there is formed "an openlng 12. The wings 6 in addition to the openings `12 are' provided ivi-th openings lei and in each of 7g the wings 7 on the section 3, openings 15 are formed. AL-issembled Ewith the openingsl 14 and 15 are straps-1 6 or like detachable securing means which', passing' transversely of forming .the subject matter of this applicaf tion upon the tire v' The openings 11 and 12 constitute a part of the means whereby the adjacent ends Vof 'the wheel rim 7 serve to hold the protector 75 certain'o the sections ot'l the protector are 30 i connected. The connecting means under consideration ,further includes a plurality of links 1 8, one ot which is shown in Fig.

6, each .link 18 comprising a body 19 provided with rectangular extensions 20' at'its g5 ends, the extensions20 terminating in heads- 2i which lie transversely ofthe body 19 'of the link. The extensions 20 of the link 18 lie in the openings 1l and 12, vand the heads 21 extend transversely vof the openings andv 90 engag'ethe inner sides of the constituent sec-4 tions of the protector. The constructionis such that link may be removed readily when the same is turned so that it stands radially of the Wheel, under which circuin- 95 stances, the head 21 may be 'withdrawn through the opening 11 ortlie opening 1st. llVhen, however, the body portions 19 of the links extend circumferentially of the Wheel,

the links cannot be detached from the sec- 10c tions, because the-heads 21. of the links extend transversely of the openings, l1 and 12. and engage the inner face of the' sections. lt will therefore be seen that although the protector by means of thev links 1S is held in. 105

operation securely upon the ivlieehfthe constituent sections ofthe protector, neverthe-- less, may be detached readily from each other when 4a mechanism to be described hereinafter is loosened, thereby permitting 1'i`o.

a slacking away of the protector. I i

ln the Wings of the section-8 are formed "2.75,- one of which is shown in Fig. 7

openings 22 and 23 ones-of which is for the In the wings 8V inv a rectangularlydisposed extension 26 having a'. transverse yhead 2T. Assembled with each lever Q5 is a link .28 having a rectangularly disposed extension 29 terminating in a transverse head 30. The links 28 arefpivotally assembled with the levers 25 ,intermediate the ends of the levers as shown at 36.A

In practical operation, the links 8 are so disposedthat they stand radially of the tire and extend outwardly. y The heads are then passed through the openings '22 and the heads 27 of thej/lev'ers 25 are passed through openings 2l. Tlien,tlie free ends of the p levers are swung inwardly toward the hub pointed of the wheel, the free ends of the levers being engaged behind hook-sliaped lips or stops 10V as will be understood clearly from Fig. el. Under the circumstances above out, the heads 30 extend transversely of the openings 2'2 and the heads 27 extend transverselyT of the openings 2l, an accidental detachment of the parts being practically impossible after the links and the levers have been disposed in their locked positions. v

Applied to each of the sections 1, 2, 3 and 4 is a circumferential tread strip 31, preferably fashioned froin steel, the strip 31 coinprising a longitudinal rib 32 intersected at intervals by transverse ribs 33. At the point of intersection between the ribs 32 and' 33, the strip 31 is assembledy with the section by means of rivets 3i or other securing means adapted to a like end.

Having thus described the invention, what is claimed is A tire protector comprising sections, one of which is provided with a stop, both of the sections being equipped with slots near their meeting ends; a leverl extended circumferentially of the protector and engaged by the stop, and a link extended circumferentially of the protector, the link being pivotally assembled with the lever, the link and the lever being provided with angular extensions lying in the slots of the respective sections, and the extensions being provided with transverse heads engaging the respective sections, the heads being removable through the slots when the link and the lever lie in an approximately radial direc.- tion with respect to the protector.

In testiniomT that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
